Alky injection
You really don't use much either if you already have an intercooler. I filled mine up about a month ago and after 2 times at the track and lots of daily driving I am still above 1/2 tank (3/4ga cell)
If your IATs stay low enough now and you have plenty of fueling then I
d say no. If you wanna turn up the boost even higher then it could definately help.
The Grand National guys usually get to 20psi before they can't go any higher without race gas. Wth Alky injection they can get to 25psi in some cases.
